Supports

When I selected Generate supports I expected none. However, the software “lifts” the model off of the platform and creates supports for the elevated model. Is this required or can I print the object with one face one the build platform?

It is possible to print direct to the platform without supports - I have not done it personally. The first ~20 layers will be “compressed” as this forms the base of the part and build plate adhesion is established

If you select “generate supports”, PF will add supports where it thinks it needs them - and will lift the model off the surface to do so regardless of surface orientation.

As for whether you need supports, the link FehlbO posted works, also take a look at this post:

Black Resin, version four; MAJOR FAIL

This is somewhat of a tangent but generally it’s advisable to avoid keeping your parts large surfaces parallel to the build plate. Resin issues aside supports and prints are much more likely to fail, in my experience, due to this than any other reason. [flat] Notice on the above example when the printer transitions from “supports” (red) to the first part layer. At that point it goes from a work area of ~Y mm^2 to like ~100 Y mm^2 in one resolution step. This leaves you with two major issues: a…
